In this activity, produced by Gatsby Science Enhancement Programme, students are presented with a range of graphical information.

Students are presented with a graph about atmospheric oxygen levels at different altitudes. They are asked questions about the graph and also pose questions to their fellow...

On 30th June in 1908 the largest asteroid in recorded history smashed into Earth in Siberia. This date is now used as an opportunity to highlight the risks of asteroids to equipment in space and the Earth; and their positive effects such as their role in the formation of the solar system and asteroid impact sites...

This collection contains a selection of videos relating to themes concerning climate change.

The first collection focuses on the rise in Carbon Dioxide levels in the atmosphere over time. The second resource offers three perspectives on...

Because of the shape of the Earth’s orbit around the Sun, it is farther away from the Sun in July than it is in January. Still, we have colder days in January than in July. How is this possible? Through this mystery, students will investigate the orbit of the Earth around the Sun and its influence on solar energy...

This Catalyst article investigates the research into artificial photosynthetic systems.

With the world’s population ever-expanding, energy demand is expected to double by 2050 and triple by 2100. In only 200 years, mankind has squandered what nature has taken hundreds of millions of years to lay down as...

Classroom Space was developed by the University of Leicester with a grant from the Particle Physics and Astronomy Research Council (PPARC). It was designed to use the context of space science and astronomy to teach science in the secondary school curriculum. The resources are: * Water on Mars? * Weathering on the...

These resources from the European Space Agency climate change initiative education resource pack allow students to learn about how the ocean circulation has an impact on the climate. This redistribution of heat around the Earth 'planetary heat pump' supplies warmer water to the poles and influences the rate at...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at how scientists are using fish scales to figure out why the UK salmon population is falling; and how carbon dioxide emissions from power stations could be used to make household bricks.

Salmon numbers...

Astronauts have been taking photographs of the Earth from space for over 50 years and Earth Observation scientists have used satellite images for a similar amount of time.

The EO Detective activities aim to demonstrate how a vantage point in space, such as the International Space Station, provides a unique...

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface...

This series of resources from Defence Dynamics uses military contexts to teach aspects of science.

*Carbon and the Carbon Cycle- two activities look at the carbon cycle, its imbalances and how carbon, in the form of fuel, is obtained.

*Conservation - an activity which...
